Application filed September 26, 1885. Serial No 178,265. (No model.)

To aZZ whom, it may concern.- 'Be it known that I, WILLIAM P. ANDREWS, a citizen of the United States, residing at Dana, in the county of Vermillion and State of Indiana, have invented new and useful Imof which the following is a specification, reference being had therein. to the accompanying drawings. I My invention relates to the class of pumps; having two or more pistons working in sepa: rate cylinders; 'and the invention consists in an improved construction adapted to be operated, as hereinafter fully set forth and claimed. In the drawings referred to,Fig.ure 1 is a per-- spective view of a force-pump havinga number of pistons and cylinders provided with r. raises-than a water-pipe.- Fig. 3 represents a horizontal section of the valve-box. Fig. 4 is a vertical section showing a modification in the construction of the Fig. 5 is a vertical section of tilting platform and other details.

Adesignates a circular valve-box having a central water-chamber, B, aroundwhich are mynnprovementsrFig arranged a number of compartments or waterpassages, a, through which water passes from the outside to the central chamber. Each of the passages a is provided with two valves 0 L, the valve 0 being placed at the outer and the valve 0 at the inner end of the passage, as shown.

0 indicates a fixed vertical shaft extending upward from the center of box A, and provided with or having formed on its upper ex tremity a ball, 6. The upper central portion of the ball is provided with a projection, (1, having a socket to receive and form the bearing of the lower end of the rotative shaft F. The projection d extends through the central opening in and forms lateral bearing for the Band at its tilting platform, drawings.

D is a tilting platform which is mounted on. the ball I), and is provided with a collar, (1, on

as shown in Fig. 5-of the its lower side, which fits over the ball and allows the peculiar rocking motion of the plat form, as hereinafter stated.

0 the platform periphery are secured the upper ends of a numberof piston-rods, f, each rod ex-,' tending downward into a cylinderfE, which is fitted in the top of the valid-box A, directly ,near its periphery,

along the periphery over and communicating with one of thecompartments or water-passages a.

F isa vertical rotative shaft above and on 5 the same line with fixed-shaft G, and stepped in the soeketed projection d on the ball b, the

platform D, which rests on the ball, having a central aperture to receive Near the lower end of said shaft, extending at right angles therefrom and adjustably fastened thereto, is an arm, at the outer end of which is journaled a heavy Wheel, h, so held in position that it bears on the platform D and as the shaft F is rotated the wheel h is caused to travel around of platform D, pressing its periphery downward below the level ofthe the projection d.

the ball 6, and as the periphery of the plat= 7o form D is pressed downward at one part, the opposite part is correspondingly raised. *This rocking motion of the wheel imparts therequisite movements to the plungers in the cyl indcrs E, the plunger-rods being connected with the tilting platform, as before stated, and

as the several pistons are thus successively operated the water is drawn through the passages a to the central chamber, B, and forced upward through a pipe, G, leading from the chamber upward, terminating in position to discharge the water as desired. The arm 9 is preferably attached to the shaft F by means of a sleeve, m, and-a set-screw, n, which al-. lows its adjustment upward or downward on. the shaft to regulate the stroke of the pistons.

The means for rotating shaft F and operating the pump mechanism may be a. crank, k, and bevel gear-wheelsp, as shown in Fig. 1, or the pnmpmay be driven by power from a wind-wheel, the device described being well adapted for operation with a wind-wheel for a motor, the stock or yertical shaft of the wheel extending from the upper end of shaft F and being keyed thereto.

When the fixed shaft 0 is made hollow and serves as a water-pipe, as shown in-Fig. 2, another pipe 0 is connected with the shaftpipe 0 just below the ball b, and is extended upward and is connected with or forms the discharge-spout.

p The cylinders E may be made of wood, glass, or any suitable material. If made of glass, they are to be set in sockets lined with ter-chamber, and valve is at or near the bottom of the well, so that the water-passages a are constantly filled by the pressure of the water.

This pump, constructed as set forth, has great advantages in its durability and ease of operation. It discharges water in a steady continnous stream, and is especially adapted for deep wells and cold climates. The construction is also well adapted for the employment of a wind-wheel for driving power, the vertical shaft F being extended by an additional shaft, on which the wind-wheel is mounted, such shaft being easily raised to its position by a simple apparatusindicatedin dottedlines in Fig. 2namely, a pulley, 1, over which is passed a rope, 2,.one end of which is attached to the axle of the vertical bevel-gear p, saidwheelbeing removed, the other end of the rope being attached to a section of pipe which is connected with the windwheel shalt. The crank it is turned, winding the rope and rais ing the shaft to 'a vertical positiomwlien it may be adjusted in connection with shaft F. The shaft being tubular and made in sections, the operation is repeated for each sect-ion added.

What I claim as new is- 1. The combination of the fixed shaitO, having the ball b, provided with the socket pro projection d, the arm 9, adj nstably attached jection d, the tilting platform I), havinga central opening to receive the socket projection,

and havingthe collard, adapted to fit over the ball, the rotative shaft'F, stepped in the socket to the rotative shaft, the-wheel h, carried by the adjustable arm, and tliepiston-rodsf, at-

-provided with the central imparting rocking motion to a SEMMO tached to the tilting platform, substantially as and for the purposes described.

2. The combination of the valve-box A, located at or near the bottom of the well and water-chamber, B, water-passages at, having valves 0 c and cylinders E, connected with the water-passages, the fixed hollow shaft 0, adapted to form a Water-pipe connected at the lower end with the waterchamber and provided at its upper portion with the branch pipe b, having the socket projection d, the tilting platform D, located at the water-level in the well and having the central opening to receive the projection d, and provided with thcdownweirdly-extended collar (1, adapted to fit over the ball, the piston-rodsf, connected with the tilting platform, and means, as set forth, for

the tilting plat form, substantially as and for the purposes described. v

' 3. The combination of the valve-box A, located at or near the bottom of the well and provided with the central water-chamber, B, water-passages (1, having valves 0 c and the cylinders E, connected with the water-passage the fixed shaft 0, provided with the ball I), having the sockcted projection d, the tilting platform D, located in the well and havingthe central opening to receive the projection d,

.and provided with the downwardly-extended collar (1, adapted to fit over the call the pistons connected with the platform D, thewator-pipe G, connected with the central waterchamber, B, and extended upward out of the -well, and means, as set forth, for imparting U and the ball rocking motion to the tilting platform, substantially as and for the purposes described.

In testimony whereof I have affixed my signature in presence of two witnesses.
